Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 446-2002 "brazed heat exchangers with aluminum composite foil."
Compared with this standard YS/T 446-2002, the main technical changes are as follows.
--- To increase the content of the composite strip;
--- Adds alloy grades;
--- Expanding the composite foil thickness, width;
--- Increased burr height and curvature of the side test methods;
--- Modified composite foil thickness, width tolerance.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Northeast Light Alloy limited liability company.
Participated in the drafting of this standard. Wuxi Silver State Aluminum Co., Ltd. Ruyuan East Sunshine fine foil Ltd., Southwest Aluminum (Group) limited liability
